The invention relates to devices applicable to railway tracks, and moreparticularly to the rail itself, for engaging car wheels to stop themovement of the car along the track.

ldh'eelstops, chocks orrail clamps for this purpose have long been inuse and their general objects` will not be detailed here as all thoseworking in the railway field are familiar therewith. f

provide asimple economical structure which may bereadily appliedV to arail without any drilling or other work on the rail; to provide meansfor easily and securely clamping or attaching the wheel stop to therail; and to adapt the device for rails of different sizes withoutrequiring the use of interchangeable parts for .dierent size-drails. v

1 Eachof the figures shows theinvention ap.- plied to a section ofordinary rail 1 which isnot a part of therinvention although the latteris only vuseful when applied to the rail. In Figure 17 he main or bodypart of the device consists of an upright casting or forging 2 having alower edge 3 arranged to overlie the top face of the/rail 1 throughouttbe length of the body. The front edge 4 of the body is shaped'tocorrespond to the contour of a car wheel. i Guide lips L depend fromthesides ofthe body. -A pair of in- The objects of the present inventionare to y 'cludes' a body member 17 overlying the rail verted V-shapedyokes 5 straddle the lower element` 6 of the body and project downwardlyat. the sides of the rail and toa point below the latter, A key l7extends transversely of each yoke lacross the lower portion thereof vandthrough suitable openings provided in the arms of the yoke at a levelwhich positions the key so that it may engage the lower face 8 yof therail flange and as the key is driven homo it wedges the yokef and member2 60 tightly against thetop of the rail whereby an vattemptto movemember 2 along the rail will be-eftfectivelyresisted by friction betweenthem. This friction will be increased because of the tendency ofany'movement of member 65.. 2V along the rail to cant yokes 5 at ganangle therebyy cooperating with the wedge structure to tightly hold thewheel stop in position.

To further Vresist movement ofthe device alongtherail, yokes 5 are sospaced -longitu- 70 dinal'y of the device and are so shaped that each isarranged to engage an upright face of a respective cross tie 9.

Y The legs of the yokes engage the edges of the rail fiange and when thedevice is tightcned, the yokes not only hold member` 2 against movementlongitudinally of the rail but also hold it upright against forcestending to overturn it.

Figures 3 and 4 illustrate a modification 80 in which' two complementaryupright members v10y and 11 are, secured to eachother throughout asubstantial portion of their Yheight and are shouldered as indicated atS to rest on top ofthe rail head. The sides of the shouldered portionsextend downwardly from the upper portions of the device to a point belowthe bottom of the rail where they are engaged by a tapered'key 12serving as a wedge to force the device downwardly as 'far' as possible.In this structure the front and rear edges 13and 14 of the upstandingplate members arev disposed to contact with the rear and front edges reyspectively of the cross ties 15 and 16 tor co- 95 operater with thewedging keys to prevent movement ofthe device along the rail.

The deviceshown inFigures 5 and 6 insubstantially throughout the lengthofthe device, yokes 18 and 19 straddling member 17 and the rail 20 withtheir lower ends constructed to receive keys 21 and to engage the crossties 22. Member 17 is grooved vertically near its forward end and thewheel engaging body member 24 has a hook 24a extending into the grooveand under the crossbar of yoke 19 whereby member 24 is pivoted at theforward end of member 17 and a coil spring 25 is received in the housing26 provided in part 24- and is seated upon a boss 27 provided thereforon member 17.

This structure provides a yielding wheel stop but utilizes the samewedge attaching member common te all. of the forms of the invention.

Figure 7 illustrates a modication of the wedge structure in which thekey 28 is more slender and a cooperating key or shim 29 is notched tofix its position transversely of the depending elements 30. lf desired,the opposing faces of elements 28 and 29 may be serrated to moresecurely retain key 28 in positiony after it has been driven home.

In each of the forms of the invention the wedge key is providedwith aplurality of holes 31 adapted to receive a Cotter pin 32 to lock the keyin position. Each modification embodies a very simple device comprisingrelatively few parts and arranged to bel applied to a rail at any pointwithout drilling the latter for bolts or other attaching elements. 'llheonly tool required for application or removal of the device is a maul orhammer or any instrument with which a blow may be struck. The device iseasily removed and shifted to another point as is frequently required onrepair track work. If the installation is to be permanent, the memberresting on the rail may be spot welded thereto as indicated at W. Thedevice has a substantial bearing along the top face of the rail whichrtends to resist any overturning of the member under the forces appliedthereto and, as previously pointed out, the wedge structure makes asingle form of the device applicable to rails of different widths andheights.

rlhe details of the invention may be further modified without departingfrom the spirit of the invention and the exclusive use of suchmodifications as come within the scope of the claims is contemplated.

llVhat is claimed' is:

1. In a device of the class described, a body part constructed to sit ontop of arail and to engage a car wheel, and means `for holding said partto the rail including a wedge structure disposed to underlie the rail.

2. Vln a device of the class described, a body part constructed to siton top of a rail and to engage a car wheel, and means for holding saidpart to the rail including elements extending downwardly from oppositesides of said part and means extending across the lower portions of saidelements and constructed to be positioned therein to seat against thebottom of the rail and to move to wedge said elements downwardly.

3. In a device of the class described, a body part constructed to sit ontop of a rail and to engage a car wheel, and means for holding said partto the rail including cooperating elements disposed to underlie the railand movable along each other to accommodate rails of different heightsand to wedge said part against the rail.

9. A device of the class described comprising a wheel engaging memberdisposed to lie along the top of a. rail, yan inverted V-shaped yokeextending over a portion of said member and downwardly therefrom, and arail bottom engaging and wedging structure extending across and throughthe sides of the lower portion of said yoke.

10. A device as specified in claim 9 in which wedging structure includesa plurality of parts interlocked with each other and with the yoke so asto retain the wedging structure tightly in wedge position.

11. ln a device of the class described, a body having a part arranged toengage the top of a. rail, means for holding said part to the railincluding a wedge structure cooperating with the bottom of the rail,said body including a pivotally mounted wheel vengaging member, and aspring structure confined between said part and member. 12. In a deviceof the class described, a. body part arranged to rest on the top of arail, a yoke with its crossbar overlying said part and with its legsextending downwardly therefrom, a wedge for engaging said legs and thebottom of the'rail, said body including a wheel lengaging member pivotedon said erossbar, and a spring structure compressed between said partand member.
